Ah, great! I rewrote this to use ...and it almost works already. I have added (service static-networking-service-type (list (static-networking (interface "lo") (ip "127.0.0.1") (requirement '()) (provision '(loopback))))) and the VM builds, only it doesn't start herd: exeception caught while executing 'start' on service 'loopback': Value out of range 0 to 4294967295: -1 I have added new code for this as a squash! commit, that I then also revert for now, until it works. :-( Greetings, janneke --=20 Jan Nieuwenhuizen | GNU LilyPond http://lilypond.org Freelance IT http://JoyofSource.com | Avatar=C2=AE http://AvatarAcademy.com
